Specification of Letters Patent.

application mea August 5, 191s. Serial No. 248,382.

To all whom it may concern.'

Be it known that I, GLEN RANDALL, a citizen of the United States,residing at Mitchell in the county of Scotts Bluil'I and State ofNebraska, have invented certain new and useful Improvements in Stock-Oilers, of which the following is a specification.

This invention relates to stock oilers and more particularly to animproved device for containing a supply of lubricant to be automaticallydistributed as contact of the animal and device is made.

The principal object of the invention is to provide an improved stockoiler which will require a minimum space and which will supply lubricantor grease to the sides and back of the animal.

A further object of the invention is to provide a device of thischaracter which consists of comparatively few parts and is simple inconstruction, but durable and well adapted to withstand the rough usageto which devices of this character are ordinarily subjected.

For a full description of the invention and the advantages and meritsthereof reference is to be had to the following description andaccompanying drawings, in which Figure 1 is a side elevation partly insection showing the device constructed in accordance with my invention.

Fig. 2 is a detail section taken on the line 2-2 of Fig. l.

Fig. 3 is an enlarged fragmentary section of a portion of the device.

Fig. 4. is a section taken on the line 4-4 of Fig. 3.

Referring to the drawings, wherein is illustrated the preferred form ofmy invention, in which like numerals of reference indicate correspondingparts throughout the several views, the upright parallel columns 1 and 2are of hollow construction being preferabl formed from suitable lengthsof pipe. A ase member 3 is provided for each column and includes a basefiange 4 adapted to be bolted to the ground or Hoor. A screw threadedextension 5 carried by the base is adapted to receive the lowerinteriorly screw threaded end of each column and the u per end of eachcolumn is normally closed y a removable cap 6.

Approximately intermediate the ends thereof, each pipe is provided witha right angularly extending projection 7. A cross pipe 8 has its endsconnected to the members 7 and thereby forms brace bar for the columns 1and 2 and also a means for oiling the back of the animals as willpresently appear.

The columns 1 and the pipe 8 are provided with a plurality of relativelysmall openings or outlet ports 9 one of which is shown to advantage inFig. 4 of the drawing. The openings are slightly ta ered as shown andcach receives a tapere valve member 10. The valve members aresubstantially conical in formation and have their outer ends eX- tendedbeyond the outer surface of the pipe and rounded as shown. The inner endof each valve member carries a stud 11 which is connected to a flatspring 12 at one end of the latter, the opposite end of the spring beingriveted or otherwise fastened to the pipe as indicated at 13. The valvemembers are thereby resiliently held in position for closing the ports 9but it will be obvious that when the animals rub against the columns thevalves will be forced inwardly and a quantity of grease or oil containedwithin the hollow columns will be permitted to pass out through theports and thereby spread upon the animals hide. The cross pipe 8 beinghorizontally disposed will act in the same manner when the animal passesbeneath the pipe since its back will contact with the pipe and force thelowermost valve into open position as set forth.

The device is especially desirable for large cattle for the reason thatit is eifectively braced by the cross pipe 8 and will withstand theweight of the animal when the latter rubs against the pipe or columns.

The foregoing description and accompanyin drawings have reference towhat might e considered to be the preferred or approved form of myinvention. I desire it to be understood that I ma make such changes inconstruction, com ination and arrangement of parts, materials,dimensions, et cetera, as may prove expedient and fall within the scopeof the appended claim.

Having thus fully described my invention what I claim as new and desireto secure by Letters Patent, is

A stock oiler comprising a pair of parallel columns of hollowconstruction, a brace pi e disposed horizontally and having its en sconnected to the said columns approximately In testimon whereof I afixmy signature in presence 0 two Witnesses.

intermediate the ends thereof, the said columns and said pipe having aplurality of openings formed therein, and ,inwerdl mow able valve meansmounted in the sai' openings und resilently held to extend beyond thesaid pipe and columns when in operative position.
